Answer:

two other angles of a triangle are 75 degree .Both two angles will be 70 degree since it is an isosceles triangle.

Step-by-step explanation:

according to the given diagram the given triangle is an isoscels triangle because it's to sides are equal

here unknown name is also c degree because the base angles of an isosceles triangle are equal.

so to find angle c

equation is :

c + c + 30 = 180 degree (sum of interior angles of a triangle)

2c + 30 = 180

2c = 180 - 30

2c = 150

c = 75 degree

If mArc BC is 105°, what is mArc CD? (3 points)

Virty [35]

Well, its a given more or less when referred to the measure of an Arc, it's usually meant the CENTRAL ANGLE made by that arc in this case, 148 is the CENTRAL ANGLE, so if BCD is 148 and BC is 105, then CD is the rest of the 148. 148 for the central angle, if we use up 105 for BC, how much is left over for CD?

Answer:

1. Vertical shrink by a factor of ¹/₅

2. Right 5

3. Up 5

Step-by-step explanation:

Transformations of Graphs (functions) is the process by which a function is moved or resized to produce a variation of the original (parent) function.

Transformations

For a > 0

$f(x+a) \implies f(x) \: \textsf{translated}\:a\:\textsf{units left}$

$f(x-a) \implies f(x) \: \textsf{translated}\:a\:\textsf{units right}$

$f(x)+a \implies f(x) \: \textsf{translated}\:a\:\textsf{units up}$

$f(x)-a \implies f(x) \: \textsf{translated}\:a\:\textsf{units down}$

$y=a\:f(x) \implies f(x) \: \textsf{stretched parallel to the y-axis (vertically) by a factor of}\:a$

$y=f(ax) \implies f(x) \: \textsf{stretched parallel to the x-axis (horizontally) by a factor of} \: \dfrac{1}{a}$

$y=-f(x) \implies f(x) \: \textsf{reflected in the} \: x \textsf{-axis}$

$y=f(-x) \implies f(x) \: \textsf{reflected in the} \: y \textsf{-axis}$

Identify the transformations that take the parent function to the given function.

Question 1

$\textsf{Parent function}: \quad f(x)=x^3$

$\textsf{Given function}: \quad f(x)=\dfrac{1}{5}x^3$

Comparing the parent function with the given function, we can see that the parent function has been multiplied by ¹/₅.

Therefore, the transformation is:

$y=\dfrac{1}{5}\:f(x) \implies f(x) \: \textsf{stretched parallel to the y-axis (vertically) by a factor of}\:\dfrac{1}{5}$

As 0 < a < 1, the transformation visually is a compression in the y-direction, so we can also say: Vertical shrink by a factor of ¹/₅

Question 2

$\textsf{Parent function}: \quad f(x)=x^3$

$\textsf{Given function}: \quad f(x)=(x-5)^3$

Comparing the parent function with the given function, we can see that 5 has been subtracted from the x-value of the parent function.

Therefore, the transformation is:

$f(x-5) \implies f(x) \: \textsf{translated}\:5\:\textsf{units right}$

Question 3

$\textsf{Parent function}: \quad f(x)=x^3$

$\textsf{Given function}: \quad f(x)=x^3+5$

Comparing the parent function with the given function, we can see that 5 has been added to the parent function.

Therefore, the transformation is:

$f(x)+5 \implies f(x) \: \textsf{translated}\:5\:\textsf{units up}$

What number makes 3 and 71 divisible by 9?

Snezhnost [94]

3 only
7 only 
1 only 
1, 4, and 7 
do you mean which digit is added to 371 so that it is divisible by 3 
test for 3, sum of digits divisible by 3 
3 + 7 + 1 = 11 
if you add 3, 11 + 3 = 14 not divisible by 3 
if you add 7, 11+ 7 = 18 divisible by 3 
if you add 1, 11+ 1 = 12 divisible by 3 
if you add 1, 4, 7 divisible by 3
